01B552 - Walter SST+ Cobalt Jobber Drill Bit - Wire Gauge #52

High-Performance Drilling for Hard Metals

The Walter #52 SST+ Jobber Drill Bit (SKU: 01B552) represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered to address the common challenges faced when drilling tough materials like stainless steel, this bit utilizes a proprietary cobalt blend that significantly enhances hardness and heat resistance. Unlike standard high-speed steel bits that dull rapidly under high thermal loads, the SST+ maintains its cutting edge longer, ensuring consistent performance even in the most demanding MRO environments.

Precision is paramount in professional applications, and the SST+ delivers with its 135° split point geometry. This "Speed Tip" design is self-centering, eliminating the need for center punching and preventing the bit from "walking" across the workpiece surface upon startup. This feature is particularly critical when working on rounded surfaces or in tight quarters where stability is difficult to maintain. The bit's body features a back-tapered construction, which minimizes contact with the hole walls, thereby reducing friction and heat generation—the primary enemies of drill bit longevity.

Chip evacuation is optimized through Walter's innovative "High Flow" flute design. By efficiently clearing debris from the cutting zone, the bit operates cooler and with less torque requirement. The exclusive bronze SST surface treatment further aids in lubricity and wear resistance. Whether utilized in a stationary drill press or a portable hand drill, the Walter #52 SST+ provides the reliability and efficiency required by professional fabricators and machinists working with mild steel, non-ferrous metals, and high-tensile stainless alloys.
